Hi ! Good evening. I am Dr Shareef answering your query. Even though it is good to be concerned about one s own health, one should not become frightened or obsessive on cancer for the kind of symptoms you have without a clinical examination by doctor, and the related investigations if any. Therefore, I would advise you to get your self examined by your family physician, who after a general examination might advise you for some proton pump inhibitor drug and a probiotic. Apart from that, you have to avoid eating from outside if you do specially any kind of oily, fried and fast food, as some components of these food items might be causing sensitivity reactions to the mucosa of your intestines resulting in such symptoms of yours. If the symptoms persist, you might have to take appointment with a gastro enterologist for further help. But I must advise you to think obsessively on it to avoid losing peace of your mind. I hope this information would help you in discussing with your family physician/treating doctor in further management of your problem. Please do not hesitate to ask in case of any further doubts. Thanks for choosing health care magic to clear doubts on your health problems. I wish you an early recovery. Dr Shareef.
